It is standard practice for BT clients to start at 6881 and go up as
high as 6889. This is semi-silly, but it does make it easier to implement
MitM caches if so desired.

Failing that, taking whichever port the OS gives to you is standard
practice. This typically starts at 1024 and goes upwards as various
programs use temporary ports.
